Removal Procedure
Personal injury can result from contact with refrigerant.
Contact with refrigerant can cause frost bite. Keep face and hands away
to help prevent injury.
Protective goggles must always be worn when refrigerant lines are
opened, even if the gauges indicate the system is empty of refrigerant.
Always use precaution when a fitting is removed. Slowly loosen the
fitting. If the system is still under pressure, release it slowly in a well
ventilated area.
Personal injury or death can result from inhaling refrigerant through a
lit cigarette.
Inhaling air conditioner refrigerant gas through a lit cigarette or other
smoking method or inhaling fumes released from a flame contacting air
conditioner refrigerant gas, can cause bodily harm or death.
Do not smoke when servicing air conditioners or wherever refrigerant
gas may be present.
Use a certified recovery and recycling cart to properly remove the
refrigerant from the air conditioning system.

1. Start the engine. Park the machine on a hard, level surface. Shut off the engine.
Personal injury or death can result from grease and oil coming out of
the relief valve.
Grease and oil are under high pressure coming out of the relief valve
and can penetrate the body.
Do not watch the relief valve to see if grease is escaping. Watch the track
or track adjustment cylinder to see if the track is being loosened.
Make sure the vent holes are clean before the tension is released on the
track.
